## Welcome to Equivalent Exchange 3!
The Compilation part (Setup) was done mostly by Minalien, I just changed it a bit. Some credit goes to BuildCraft's README.md, which I based this README off of.

### Compiling Equivalent Exchange 3
IMPORTANT: This is not guaranteed to work as it has not been tested extensively (only done on Linux so far, partly on Windows).
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
#### Setup MCP
1. Create an empty directory for EE3 development. This directory is referenced as `mcdev` from now on.
#### Prerequisites (Tested for Windows 7 ONLY!)
1. Download and install the Java JDK [here](http://www.oracle.com/technetwork/java/javase/downloads/jdk7u9-downloads-1859576.html). Just scroll down.
* Go to `Control Panel\System and Security\System`, and click on `Advanced System Settings` on the left-hand side.
* Click on `Environment Variables`.
* Under `System Variables`, click `New`.
* For `Variable Name`, input `JAVA_HOME`.
* For `Variable Value`, input something similar to `;C:\Program Files (x86)\Java\jdk1.7.0_09` exactly as shown to the end.(or wherever your Java JDK installation is), and click `Ok`.
* Scroll down to a variable named `Path`, and double-click on it.
* Append `;C:\Program Files (x86)\Java\jdk1.7.0_09\bin` (or wherever your Java JDK installation is \bin), and click `Ok`.
2. Download and Apache Ant [here] (http://ant.apache.org).
* Unzip the files anywhere you want, eg `C:\Program Files (x86)\Ant`.
* Again, go to `Environment Variables` just like you did for the Java JDK.
* Under `System Variables`, click `New`.
* For `Variable Name`, input `ANT_HOME`.
* For `Variable Value`, input `C:\Ant\apache-ant-1.8.4` (or your Ant directory \apache-ant-1.8.4).
* Scroll down to `Path`, and double-click on it.
* Append `;C:\Ant\apache-ant-1.8.4\bin` exactly as shown to the end (or your Ant directory \apache-ant-1.8.4\bin).
3. Download and install Github [here] (http://windows.github.com/).
* Create an account.
* Go back to the Equivalent-Exchange-3 directory [here] (http://github.com/pahimar/Equivalent-Exchange-3).
* Click `Clone to Windows` near the top-left of the page.
* You should see Github flash and `pahimar/Equivalent-Exchange-3` appear. (The local repository defaults to `C:\Users\(username)\Documents\GitHub\Equivalent-Exchange-3`, you can change it if you want but then you have to find it again on Github).
4. Create an empty directory for EE3 development. This directory is refernced as `mcdev` from now on. It can be where you cloned EE3, but it'll be a little messy.
5. You are now ready to Setup MCP!
#### Setup MCP (Linux and Windows 7 tested)
2. Download the latest version of MCP from [here] (http://mcp.ocean-labs.de/index.php/MCP_Releases) , e.g. mcp723.zip. Install MCP dependencies as listed on the website if neccessary.
3. Install Apache Ant [here] (http://ant.apache.org.)
3. Inside `mcdev`, create a directory named `mcp` and unzip the MCP ZIP file into it
4. To verify, check if a file name `CHANGELOG` exists inside the mcp directory.
3. Inside `mcdev`, create a directory named `mcp` and unzip the MCP .zip file into it.
4. To verify, check if a file name `CHANGELOG` exists inside the `mcp` directory.
5. Get a clean (unmodded!) copy of minecraft. Currently EE3 runs on 1.4.5 but that might have changed.
6. From your .minecraft directory, copy the bin and the resources directory to the `jars` directory inside `mcp`.
7. Get a clean (unmodded!) copy of minecraft_server.jar and also place it into `jars`.
8. Download the latest forge source for Minecraft 1.4.5 and unzip it into `mcp` so that `mcp/forge/install.sh` exists. You need at least Forge 6.4.0.xxx, best way is to get it from [here] (http://files.minecraftforge.net/).
6. From your `.minecraft` directory (on Windows, defaults to `%appdata%\.minecraft`), copy the `bin` and the `resources` (I don't think you need resources on Windows 7) directory to the `jars` directory inside `mcp`. (I actually believe Forge's installation might do it for you)
7. Get a clean (unmodded!) copy of `minecraft_server.jar` and also place it into `jars`. (Forge might do this for you)
8. Download the latest forge **source** for Minecraft 1.4.5 and unzip it into `mcp` so that `mcp/forge/install.sh` exists. You need at least Forge 6.4.0, best way is to get it from [here] (http://files.minecraftforge.net/).
9. Execute `mcdev/mcp/forge/install.sh` or `mcp/forge/install.cmd`, depending on your platform. On Linux you might have to `chmod +x` `install.sh` before you can execute it. On some system configurations you need to execute `install.sh` from within the forge directory whereas on others it doesn't matter. Just check the output for error messages to find out what you need to do.
#### Setup EE3
1. Inside `mcdev`, create a directory named `source`. Clone EE3 into this directory.
2. [FOR WINDOWS] Open up cmd. Type `cmd` in Run.
3. [FOR WINDOWS] Navigate to `mcdev\source` by executing `cd [wherever your mcdev is located, just copy and paste the path in]`. (eg cd C:\Users\Username\Documents\mcdevname\source)
2. Inside `sources\Equivalent-Exchange-3` execute `ant build -Ddir.development=../../`. If you've done everything right, BUILD SUCCESSFUL is displayed.
3. Execute `ant recompile -Ddir.development=../../`.
4. Execute `ant reobfuscate -Ddir.development=../../`.
5. If you've done everything right AND the source code currently compiles, you can execute startclient.sh or startclient.bat inside the mcp directory now to start Minecraft with EE3.
#### Setup EE3 (Some tested for Linux, some for Windows)
1. Inside `mcdev`, create a directory named `source`. If you're doing this from the default clone directory, make two folders: `source` and `Equivalent-Exchange-3`. Copy and paste the original files into `Equivalent-Exchange-3`, and then move that into `source`.
2. If you haven't already, move/clone `Equivalent-Exchange-3` into `source`.
3. Right now, you should have a directory something like:
(I currently can't find the .jar file anywhere inside `mcdev`, so you can just go into `mcdev\mcp\reobf\minecraft` and zip the ee3 folder.)
***
mcdev
\-mcp
\-A whole bunch of mcp files, including CHANGELOG.
\-forge
\-jars
\-source
\-Equivalent-Exchange-3
\-EE3's files, including build.xml.
***
4. Inside `Equivalent-Exchange-3`, create a new file called `build.properties`.
* Open it up, and type into it the following:
* `dir.development=../../`
* `dir.share=Shared` (or what you want it to be)
* `dir.release=Releases` (what you want it to be)
* `release.minecraft.version=1.4.5` (as of 11/21)
* `release.mod.version=pre2` (or whatever you want it to be)
5. [FOR WINDOWS] Open up `cmd`. Type `cmd` in Run.
6. [FOR WINDOWS] Navigate to `mcdev\source` by executing `cd [wherever your mcdev is located, just copy and paste the path in]`.
7. Inside `sources\Equivalent-Exchange-3` execute `ant release`. If you've done everything right, BUILD SUCCESSFUL is displayed.
8. Go to `mcdev\source\Equivalent-Exchange-3\Releases\1.4.5\pre2` (or whatever you put into `build.properties` for `dir.release`, `release.minecraft.version`, and `release.mod.version`). You should see a .jar named `ee3-universal-pre2.jar` (or whatever you put into `release.mod.version`).
9. Copy the jar into your Minecraft mods folder, and play Minecraft!
### To Update EE3 (For Windows Only?)
1. Check to see if pahimar updated EE3 since you last compiled. If he/she did, follow these instructions.
2. Open Github.
3. Double-click on pahimar/Equivalent-Exchange-3.
4. At the top, there is a button named `Sync` (or `Refreshing...` if its still checking).
5. Click `Sync`, and wait for it to finish.
6. Re-compile (or move it to `mcdev\source` then re-compile, depending on what you did.)
